FIREPLACE-DAMPER.

Specification of Letters Patent.

Patented July 8, 1919.

Application filed August 12, 1918. Serial No. 249,396.

To all whom it may concern:

Be it lmown that I, CHRISTIAN URs'rRoM, citizen of the United States,residing at Seattle, in the county of King and State of \Vashington,have invented certain new and useful Improvements in Fireplace- Dampers,of which the following is a specification.

This invention relates to improvements in fireplace dampers.

The object of the invention is "to provide specific means forconveniently operating a damper from the inside of the fireplace, andarranging the mechanism between the operating handle and the damper insuch manner as to be readily operated within the fireplace.

The drawing represents a perspective view of a damper and its operatingmechanism mounted in connection with a fireplace.

Referring more particularly to the drawing numeral 1 indicates the sidesof a fireplace and 2 a back wall. My dam-per is pivotally mountedintermediate the walls 1 and comprises half damper members 3 and 4:which are adjustably connected together by a screw 5 which passesthrough a slotted.

hole 6 in half member 4 and engages a threaded hole in half member 3.The damper is pivoted by means of trunnions 7 one of which is fastenedto an arm 8 on its end which is outside of the wall 1. A right angularrod 9 is pivoted to the free end of arm 8 and passes through an opening10 in wall 1 so as to be accessible from the inside of the fireplace.The position of the damper with respect to the throat of the fireplaceis regulated by moving the hand rod 9. It will be apparent thatapplicants damper can be placed within the fireplace after it is builtby first drilling holes for the trunnions 7 and adjusting and securingtllie halves of the damper after they are in ace.

While I have shown a particular form of embodiment of my invention, I amaware that many minor changes therein will readily suggest themselvestoothers skilled in the art without departing from the spirit and scopeof the invention, and I therefore desire to avoid being limited to theexact form shown and described.

Having described my invention, what I claim as new and desire to protectby Letters Patent, is

In combination, a fireplace provided in one side wall with a verticalslot, and in both side walls with alined bearings, a sectional damperextending across the fireplace and having the adjacent ends of thesections overlapping, means for adjustably fastening the overlappingends of the damper sections together, a trunnion on each damper section,said trunnions being mounted in the alined bearings, an arm on the endof one of the trunnions, and a right angular hand rod having its 'upperend pivoted to one end of the arm and its lower end extended through theslot in the side Wall to be accessible from the inside of the fireplace,whereby when the lower end of the hand rod is vertically moved in itsslot, the damper will be opened or closed.

In testimony whereof I afiix my signature in the presence of twowitnesses.

CHRISTIAN URSTROM.
